Abstract

The invention provides a single-component acrylic adhesive which comprises the following components in parts by weight: 70-90 parts of a soft monomer, 4-10 parts of a hard monomer, 1-10 parts of a functional monomer, 3-8 parts of a heat-resistant modified monomer, 0.1-0.5 part of an initiator, 100-150 parts of a solvent, 0.3-1 part of an antistatic agent and 0.1-0.5 part of a curing agent, the curing agent is glacial acetic acid and aluminum acetylacetonate. The aluminum acetylacetonate curing agent compounded by glacial acetic acid is added in the preparation process, so that on one hand, the stability of the adhesive is improved, on the other hand, the coating time and the storage time of the adhesive are prolonged, the coating time of the adhesive is prolonged to 8.5-10.5 h, the adhesive does not gel, the storage time reaches 6-8 months, the production efficiency is effectively improved, and the production cost is reduced. And the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of acrylic adhesives, in particular to a one-component acrylic adhesive and its preparation method and application. Background technique [0002] PET protective film is widely used in various fields, such as automobile manufacturing, electronic component manufacturing and life, etc., especially in the process of manufacturing and shipping protection of FPC, PCB and mobile phone electronic components, when encountering high temperature environment, it is required to use pressure sensitive The adhesive has high temperature resistance, and there is no residual adhesive on the protected surface after high temperature use, and the peeling force does not increase significantly after high temperature and is easy to peel off. During the use of the PET protective film, static electricity is generated by mutual contact and friction. Especially in a dry environment, static electricity is a great safety hazard, which wi...
